I try to change respawn tty to some other bin file , before that I configure that on /etc/inittab But now this file doesn’t exist ; how can I do that ? ( my goal is “ call my binary instead of tty ” )


/etc/inittab is the configuration file of classic SysVinit. Debian 9 uses systemd instead by default, although I think you still have an option to use another init system if you wish.

With systemd, the getty processes (= those responsible for handling login prompts on TTY devices) are managed by getty@.service which is defined by file /lib/systemd/system/getty@.service. If you want to modify it, you can either use systemctl edit getty@.service to automatically create a partial override file, or copy the file from /lib/systemd/system/ directory to /etc/systemd/system and then modify it; a customized file in /etc/systemd/system will override a standard file with the same name at /lib/systemd/system.

You should not modify any of the files in /lib/systemd: if you do, your changes may be overwritten in the next systemd update. Instead make your changes and additions in /etc/systemd/: that's what it's for.

  • You can also use systemctl edit --full to copy the unit file in its entirety and edit it. – Stephen Kitt May 19 at 17:57
